CAST IRON
Cast Iron
There are four basic types of cast iron - white iron, gray iron, ductile iron and malleable iron
There are four basic types of cast iron
white iron
gray iron
ductile iron
malleable iron
White Cast Iron
Characterized by the prevalence of carbides, impacting
high compressive strength
hardness
good resistance to wear
Gray Cast Iron
Characterized with graphite in the microstructure, giving
good machinability
good resistance to wear and galling
Ductile Cast Iron
Gray iron with small amounts of magnesium and cesium which nodulates the graphite, resulting
high strength
high ductility
Malleable Cast Iron
White cast iron heat-treated to improve
higher ductility
